垃圾厂商的BD去对抗HD阵营的主将。明显不对板。
而且XA1经过2次厂商软件升级自然很成熟了。等sony的来比较吧~
ps现在xa1 8万日元不到就能买到,真便宜。
其实主要不是机子,而是BD光碟的容量和编码的问题。 大家看好的SONY关于更大容量的承诺在量产上遇到了问题,并且难以在近期解决。因此,如果不改变MPEG2的编码格式的话,25G的BD光盘将不足以承载2个多小时的电影。 目前BD推出的电影大多为100分钟左右的。标榜大容量的SONY如今却在容量上落后,说明:1. SONY过度宣传;2. BD技术的成熟性和可实现性上不如HD DVD。 下边是微软DIGITAL MEDIA DIVISION 副总裁MAIR今天在AVS上的一段话:
“Officially, Sony has only announced 2 titles or so in BD-50 and I believe Fox said they would do a couple too. The rest are in SL-25.
As I have commented, BD-50 is not a process that goes from zero to 100%. Even when the discs can be made, yields will be so low, and the costs so high, that they will lose money on every disc they make (by as much as hundreds of dollars on each one!). So they would want to limit distribution until they get a handle on yields. I do not expect yields to become reasonable for 2+ years and maybe a lot longer.
As a way of reference, they have worked 5 years on SL-25 and the yields are still way below HD DVD-30 and cycle time (how long it takes to make a disc) 50% higher than HD DVD. As such, no one should expect BD-50 to appear quickly and go mainstream.
Of course, Sony could make a PS3 style decision and go for bust once more. But with studios like Warner producing 1 billion DVDs a year, that gamble is pretty much out of the picture.... ” |
